775 pro shield
 

The 775 has worked wonders for our team's shooting mechanism, but we noticed the wire connections were quite vulnerable (prone to bending) and because they were placed on a moving part we worried about breaking them in competition. I couldn't seem to find anything to guard the motor connections, so to fix this I created a 3d printed shield to guard them and wanted to share it with anyone else who could make use of it!



The part uses a zip tie around the outside to hold it on the motor and keep anything from pulling on the wires, and comes complete with vent ports.



Here is the part file in in stl form

Hope it helps!

This is definitely something we're interested in! I'm concerned that the part looks like it closes off the 4 rear vent holes on the very back of the 775. Is this actually the case (no pun intended)?

Re: 775 pro shield
 

They're hard to see but there are holes in the part right over the vent ports so it doesn't block ventilation :)

Re: 775 pro shield
 

This is awesome! I'm so grateful that you shared the file. We might use this if the EkoCycle can print them well. Are you soldering the wires onto the terminals or using a connector? I guess the connectors might not fit into the case.

Thanks!

Cool, we'll get some 3D printed then. Thanks for saving us a bit of design work this weekend :D

Re: 775 pro shield
 

Our team has been soldering short cables on, then attaching that with a connector other things, we printed ours out with an EkoCycle too!

Re: 775 pro shield
 

This is an awesome idea. Thanks for the post and files!

Re: 775 pro shield
 

Wow
You just took something off my list of things to do!!

Thanks a bunch for sharing!!

Re: 775 pro shield
 

Awesome, thanks.

Now if someone would just design an adjustable mount for a AndyMark Hall sensor I would be set :)

Re: 775 pro shield
 

I just got a quote on Shapeways.com - about $15 per shield + $5 for shipping, delivery by March 3rd.

Not a bad investment if your 3D printer's being annoying.

I would recommend 3dhubs. Sometimes the hubs will even give you parts for free when they find out who you are.

Re: 775 pro shield
 

Firstly, I'd like to thank you for sharing this fantastic design. Secondly, we need to make the grooves for the terminals a little wider in order to fit over our solder joints and it would be greatly appreciated if you could share the file as a Step or some other format that is more modification friendly than stl.

Thanks!

Re: 775 pro shield
 

Out of curiosity, how are you actually connecting the wires to the motors? The connectors we use look like they would be too long for this to work.

EDIT:

Nevermind, I'm blind...

Could you post a picture of how you have these attached anyways? I'm still curious about how you've soldered the wires to the motors.

Re: 775 pro shield
 

I'll take a picture of how we've soldered them and post it here tonight.

The make great salt shaker coasters too. :)

Re: 775 pro shield
 

We have been using a similar 775 cover for a couple of years. It has some compliance to the fit and clamps on with a clamping screw. Ventilation holes provide for cooling. There is room for standard spade terminals, and the wire exit hole can be turned to whatever orientation is best.

Re: 775 pro shield
 

What do you do to connect the wire to the motor?

Re: 775 pro shield
 

I appreciate seeing a more official version of this... Team 2619 has been utilizing cut pieces of PVC tubing that slide over the motor to protect our wires...

My apologies for the poor photo quality, this was the best angle I could find.
